What is Karpenter and what is its main purpose?

Karpenter is an open-source project from AWS designed for automatic scaling of Kubernetes clusters. Its main purpose is to dynamically create and delete nodes in the cluster based on current load and pod requirements. Karpenter helps optimize resource utilization, reduce costs, and increase cluster efficiency.

Example of use: if new pods requiring resources appear in the cluster, Karpenter will automatically create new nodes with the necessary characteristics, and when the load decreases, it will remove excess nodes.
